Different Approach to the Lacrimal Sac Area

Different approach to the lacrimal sac area.

THE USUAL approach to the lacrimal sac and the area around is through the standard curved incision, with the centre of the concavity about 2-3 mm. from the inner margin of the inner canthus. It can be termed "adequate", although, to get a good view and to have freedom of manoeuvre, the incision has often to be widely stretched in all directions. Even then, one is often working in a fairly deep ...

Sac over the sac - a rare case of subcutaneous dirofilariasis over the lacrimal sac area.

It was clinically diagnosed as a lacrimal abscess and was incised under local anaesthesia. A live coiled worm was found and removed along with the cyst.

Applied Endoscopic Anatomical Evaluation of the Lacrimal Sac

Introduction: Dacryocystorhinostomy (DCR), a popular surgical procedure, has been performed using an endoscopic approach over recent years. Excellent anatomical knowledge is required for this endoscopic surgical approach. This study was performed in order to better evaluate the anatomical features of the lacrimal apparatus from cadavers in the Isfahan forensic center as a sample of the Iranian ...

Carcinoma of the lacrimal sac.

Hemangiopericytoma of the lacrimal sac.

Hemangiopericytoma (HPCT) rarely originates in the lacrimal sac; 7 cases have been reported previously and only 1 contained an ultrastructural study. In this article we report an additional case and review the previous reports. While the initial biopsy specimen showed nonspecific cytologic abnormalities, light and electron microscopic studies on the subsequently excised tumor demonstrated that ...
